A while ago I posted some queries on here about how to do different things for a database, I've since had to perform other tasks so this dropped down the priority list, but now I have a bit of free time it has come back again.
I have a problem with my cascading combo boxes, which I was told how to do on the following thread: https://www.accessforums.net/showthread.php?t=58037.
When attempting to insert information on the "AddAssessor" form, all is fine until I click the "Add" button, where the following box appears:
I have made sure that there was information entered into the indicated field at the time. Once this box appears, I am then unable to close the form or proceed without losing the information I entered.
I have included the database I am using, to assist your diagnosis.
Your assistance in this matter is much appreciated.
